Since grapefruits are rich in Vitamin C, they support your immune system by reducing the cold symptoms or their severity. It also prevents damage by free radicals and also minimizes severity of inflammatory conditions such as stroke, rheumatoid arthritis, heart attack, asthma and osteoarthritis.

Grapefruit pulp contains glucarates which are compounds that help in fighting various cancers like lung, mouth, skin, colon, stomach and breast cancer. Grapefruits also contain limonoid, which are also phytonutrients that inhibit the formation of tumors by elevating glutathione S-transferase (detoxifying enzyme) formation. This enzyme triggers a reaction in your liver making the toxic compounds soluble in water for excretion.
